Method for the fully automatic loading and pellets removal from a milk of lime - softening reactor and apparatus for carrying out the method

摘要

A method for operation of a reactor (1) for softening of water, in which milk of lime and untreated water are mixed together, in which there is a granular solid is located, which by the water pressure is stirred up to a fluidized bed, wherein at the granular solid lime is deposited, as a result of which ever increasing lime - pellets are formed which, in the case of exceeding a certain size are removed, whereby continuously a for the size of the lime - pellets of relevant measured value is recorded and in the case of exceeding a predetermined limit of this measured value a removal of the lime - pellets is introduced by means of a draw-off device, and wherein, in a subsequent to this, by means of a conversion factor calculated amount of the granular solid provided for this purpose via the pipe connection is fed into the reactor,characterized by the,that the relevant measured value by a first pressure measurement (6 '') at the height of the fluidized bed in the reactor, a second pressure measurement (6 ") at the height of the pellets removal openings, as well as by determination of the differential pressure is determined,that in a function of the measured differential pressure a trigger..
